SIP integrator

[IPOfficeIreland]

anyone know of a sip integrator piece of kit which is configurable between a proxy and end user aka Avaya pbx?

running into problems with a provider which I 100% have to use but the lack of configuration settings on the Avaya pbx is limiting what we can do to integrate the 2.

With an inbetween device I could easily configure to suit both parties.

thoughts welcome!

What is it that you can't configure on the IP Office that they require?

We use the Vega Boxes. Find these offer some fantastic features. Including support for faxing etc.

its a long story Kyle. it has to do with the way avaya handles sip messges, invites, media change and update refer. there is simply nothing i can do with the rfc's which are used.

I work with a few other Pbx brands which allow you to change almost everything, which is really what you want, not every provider is going to have exactly as avaya needs, spoilt little brat!

 

[ProviderReborn]

TT, you seen it too. They really need to look at allowing the ability to map Cause codes. This would be great.

Also have you come accross issues on SIP Transfers assisted working fine, but trunk to trunk and blind tranfers giving call set up but now speech.

vega boxes, very good idea Chumpy. do you use them on your sites for sip integration?

what are the downfall points? do i loose cli or is there a maximum of calls? i need something that will handle 50 simultaneous sip calls and growing.

when avaya get more sip calls than they can handle the system crashes, great! plus the fact that it uses 2 vcms per ip call, and have speech problems every 10 calls.

are they expensive?

By the time you have specced up the IPO for VCM channels/Lics it does turn out competitive.

They do BRI and PRI30 boxes. I like them.
You can manipulate dial plans to do what the hell you want. So you could get the Vega to send to the SIP Provider codes to turn on cli, withhold cli. etc.

Its also nice that you can do fall back from the VEGA to your ISDN trunks.

The only downfull I have seen with them is the fact they use the PRI to transport. This could cause a bottle neck if you were expecting the VEGA to give you extra trunks.

absolutely, sip is one of the main fuelling reasons to get a new pbx and is the trend is towards sip trunking. i was hoping 4.2 would have more funtionality but it doesn't. plus if you make any slight change to a URI you need to reboot.

I had the voice problem on t2t but turning off reinvites fixed it and setting the codecs to uncompressed, rather than g729. thumbs up there!

But it's hit and miss with sip, you just can't go in blind and say yes it will work. it barely works, and will kick you in the butt when you try and do something simple.

we keep typing at the same time!

I already have 64 vcms licensed (30 simultaneous calls - which often gets overloaded and crashes) so plenty of room here. Do you know how much the dual pra model is?

You have seen my SIP Woes thread. The Vega has been a very close friend to us.

I'm about to step into some more SIP integration. What features are you missing or problems are you having due to the RFCs the IP Office uses? Or is it more of a compatibility thing?

sip is becoming a no go area for us too.

duffman - that's just it ipoffice uses certain rfcs (as on knowledgebase) in how it responds and carries out sip processes. What would be fantastic is the support of a least 2 rfcs per role so that we could choose the option needed.

Rather than a closed door situation and very little paperwork to aid. so compatibility, yes, or rather lack of trying to be compatible!

for example, sip proxys have a registration timer - every sip device i have ever programmed can be configured to mathc except avaya.

ALG support? not a hope!

Reinvites? never worked correctly, never sends a reinvite message so who knows what this does.

update refer - the more common and better version of reinvite - hell knows!

We have one Vegastream gateway. Calls come in on SIP, Vega then spits out BRI to an INDeX. Customer loves it.

Been installed for a year and never been back to site since it was installed.

They released some cheaper gateways last year (Vega Europa??) that brought the prices down a hell of a lot.

Only problem we had was getting hold of one. They had massive manufacturing issues which I would assume have now been sorted. They shifted the works from Wales to Canada and it all went Pete Tong!!!!

Vega Europa, A smashing wee product.

We use these alot, If a site moves into a different area or where numbers cannot be ported, we use this very item.

Get the number ported into our core and we can do whatever we want with it.

Very reliable too, and can be tweaked in many ways. I am a big fan of these as you can tell.

I must just be lucky as I haven't had an issue with any provider we have used thus far. I'll just keep my fingers crossed that we don't run into any of these issues.

Vega is good but AudioCodes is a lot cheaper and works also great.

Anyone use the Adtran Total Access 900 series IAD for this?
